Abstract
毙百虫水乳剂由重量百分比含量为5-15%的十二烷基磺酸、1.5-5%的氢氧化钠、15-40%的蒸馏水、3-10%的磷酸、3-9%的苯酚、12-30%的乙醇、0.1-0.5%的阿维菌素、2-8%的茶皂素、2-7%的硼酸、5-15%的甲苯、0.1-0.5%的香精配制而成。其生产工艺是将氢氧化钠、十二烷基磺酸、蒸馏水按比例配制十二烷基磺酸钠，用甲苯分别将阿维菌素、茶皂素、硼酸溶解成溶液，然后将其余原料及用甲苯溶解成的三种溶液倒入十二烷基磺酸钠溶液中搅拌2-4小时，搅拌温度为70-80℃，pH值为2-3。该水乳剂具有高效杀虫、低毒无环境污染的特点。
Description
技术领域
本发明涉及农业上的一种杀虫药剂及其生产工艺，具体是指一种毙百虫水乳剂及其生产工艺。
背景技术
现在，我国用于农、牧业生产以及家庭卫生方面的防治病虫害的农药，主要是采用高毒性的有机磷、氨基甲酸酯、拟除虫菊脂类等有机化学物质复配而成。在生产和使用这些农药的过程中，生态环境遭到严重的污染和破坏，人们的身体健康和安全受到严重影响。高农残的农作物商品使得消费者望而生畏，这就严重地阻碍了农业生产和国民经济的迅速发展。
低毒的生物源和植物源农药，虽也已经生产销售使用，但杀虫效果不很明显，很难控制虫情的漫延，往往给农民造成不必要的损失。
发明内容
本发明的目的，乃是为了解决现有农药存在着的或是高毒性而污染环境、或是虽然低毒性但杀虫效果不很明显的问题，提供一种低毒、高效、广普、环保型的毙百虫水乳剂及其生产工艺。
本发明的解决方案如下。这种毙百虫水乳剂是采用下列重量百分比的原料混合配制生产而成的：5-15％的十二烷基磺酸、1.5-5％的氢氧化钠，15～40％的蒸馏水，3～10％的磷酸，3-9％的苯酚，12-30％的乙醇，0.1～0.5％的阿维菌素，2-8％的茶皂素，2-7％的硼酸，5-15％的甲苯，0.1-0.5％的香精。
本发明毙百虫水乳剂的生产工艺过程是：将氢氧化钠、十二烷基磺酸、蒸馏水按1∶4∶12的比例配成十二烷基磺酸钠溶液并装入搅拌机；按配比用甲苯将阿维菌素、茶皂素、硼酸分别充分溶解，得阿维菌素溶液、茶皂素溶液和硼酸溶液；按配比将磷酸、苯酚、乙醇、阿维菌素溶液、茶皂素溶液、硼酸溶液、香精按先后顺序缓缓倒入搅拌机内的十二烷基磺酸钠溶液中进行搅拌2～4小时，搅拌反应时的温度升至70-80℃，PH值控制在2～3之间，冷却成常温后，用灌装机将药液装入容器密封并进行包装。
采用上述配比的原料和工艺制得的本发明毙百虫水乳剂，它是以化学原料、生物和植物源为原料经化学反应而制成的的一种复配农药。其杀虫原理主要是抑制害虫胆碱酯酶，使害虫神经中毒。它以触杀为主，兼有胃毒、内吸作用，破坏害虫皮肤细胞结构，使害虫皮肤腐烂而死亡。
经试验表明，该药剂对水稻、蔬菜、果木、花卉、烟草、棉花等作物上的鳞翅目、双翅目、单翅目、半翅目及各种螨类、蚜虫等害虫均有显著的杀灭效果。其特点是：①低毒：经口、经皮LD50＞2000mg/kg，对人、畜、鱼、乌等天敌无毒害：②残留毒小：所喷洒过的作物的农残不会超过国际标准，无致畸、致癌作用：③高效：经湖南、上海、江西、湖北四省市权威试验单位试验，杀虫效果均达到93～98％，使用第一天害虫死亡率在50％以上；④生产和使用过程中无三废，有益于保护环境。
具体实施方式
实施例一：取十二烷基磺酸10Kg、氢氧化钠2.5kg、蒸馏水30kg、磷酸7kg、苯酚6kg、乙醇25kg，阿维菌素0.2kg，茶皂素3kg，硼酸3kg、甲苯13kg，香精0.3Kg；将以上氢氧化钠、十二烷基磺酸、蒸馏水配成十二烷基磺酸钠溶液并装入搅拌机；用以上甲苯将以上阿维菌素、茶皂素、硼酸分别充分溶解，得阿维菌素溶液、茶皂素溶液、硼酸溶液；将以上磷酸、苯酚、乙醇、阿维菌素溶液、茶皂素溶液、硼酸溶液、香精按先后顺序缓缓倒入搅拌机内的十二烷基磺酸钠溶液中进行搅拌2小时，搅拌反应时的温度控制在70℃，PH值控制在2，冷却成常温后，用灌装机将药液倒入容器密封并进行包装。产品经田间药效试验，稀释500倍喷杀菜青虫，杀虫效果为93％，但使用中要注意的是，若稀释浓度在150倍之内，则对部分作物有伤苗现象。
实施例二：取十二烷基磺酸8kg、氢氧化钠2kg、蒸馏水24kg、磷酸10kg、苯酚9kg、乙醇28kg、阿维菌素0.3kg、茶皂素3.5kg、硼酸3kg、甲苯12kg、香精0.2kg；将以上氢氧化钠、十二烷基磺酸、蒸馏水配成十二烷基磺酸钠溶液并装入搅拌机；用以上甲苯将以上阿维菌素、茶皂素、硼酸分别充分溶解，得阿维菌素溶液、茶皂素溶液、硼酸溶液；将以上磷酸、苯酚、乙醇、阿维菌素溶液、茶皂素溶液，硼酸溶液、香精按先后顺序缓缓倒入搅拌机内的十二烷基磺酸钠溶液中进行搅拌2.5小时，搅拌反应时的温度控制在75℃，PH值控制在2.5，冷却成常温后，用灌装机将药液倒入容器密封并进行包装。产品经田间药效试验，稀释500倍喷杀菜青虫，杀虫效果为96％，但经口毒性检测LD50＞2000mg/kg，并有伤苗现象。
实施例三：取十二烷基磺酸12kg：氧氧化钠3kg、蒸馏水36kg、磷酸7kg、苯酚5kg、乙醇22kg、阿维菌素0.2kg、茶皂素3kg、硼酸2.5kg、甲苯9kg，香精0.3kg；将以上氢氧化钠、十二烷基磺酸、蒸馏水配成十二烷基磺酸钠溶液并装入搅拌机；用以上甲苯将以上阿维菌素、茶皂素、硼酸分别充分溶解，得阿维菌素溶液、茶皂素溶液、硼酸溶液；将以上磷酸、苯酚、乙醇、阿维菌素溶液、茶皂素溶液、硼酸溶液、香精按先后顺序缓缓倒入搅拌机内的十二烷基磺酸钠溶液中进行搅拌3.5小时，搅拌反应时的温度控制在80℃，PH值控制在3，冷却成常温后，用灌装机将药液倒入容器密封并进行包装。产品经田间药效试验，稀释500倍喷杀菜青虫，杀虫效果为98％。经口毒性检测数据，LD50＞2580mg/kg。稀释浓度100倍时，也未发现有伤害苗的现象，可见按上述配比制成的药液效果最为理想。
